Q: Can a sterile supply corridor that feeds the back of Surgical OR’s have a corridor of less than 8′ if the patient access is from the front of the OR? This front patient access provides the required exit access for inpatients to two exits.
A: Maybe. It all depends on whether or not the sterile supply corridor that feeds the back of the Surgical ORs could in any way be considered a path of egress for the inpatients receiving treatment in the OR. Is this path marked with ‘Exit’ signs? That is usually a dead-giveaway since it marks the path of egress through the sterile corridor as a means of egress for the occupants of the ORs. But, that is not the only indication. Even if the path is not marked with an ‘Exit’ sign, it could still be considered a required path of egress from the ORs. You mentioned that the front patient access provides the required exit access for inpatients to two exits. If that is true (and I have no reason to doubt you), then that may possibly make the sterile corridor to NOT be a required means of egress, and then it would not have to comply with section 184.108.40.206 (2000 edition) for 8 foot corridor widths for new construction. For existing construction, section 220.127.116.11 says 4 foot width is required, but if the corridor is already constructed to a width greater than 4 feet, then you must maintain to corridor to 8 feet of width if you make any alterations or renovations. Parking equipment in a corridor would be considered an alteration.
Before you make any changes to your facility, you need to discuss this issue with the architect who designed the egress routes from the ORs, if that person is still available. It is important that any change in function be reviewed by the proper individuals, which may also include your local or state authorities.
